Product details
Overview
74LVC1G66GS,132 from NXP Semiconductors is a single-pole, single-throw (SPST) bilateral analog switch with active-HIGH enable (E), two bidirectional I/O terminals (Y and Z), and operation across 1.65 V to 5.5 V supply. It delivers 6 Ω typical ON resistance at 5 V, supports ±32 mA switch current, and features Schmitt-trigger enable for robust noise immunity. It is used in signal routing for portable audio, sensor multiplexing, and level-shifting interfaces.
For engineers reviewing the 74LVC1G66GS,132 datasheet, 74LVC1G66GS,132 pinout, 74LVC1G66GS,132 application, or 74LVC1G66GS,132 equivalent, key selection criteria include its XSON6 (SOT1202) 1.0 × 1.0 × 0.35 mm package, −40 °C to +125 °C temperature range, low charge injection (5.0 pC at 3.3 V), and rail-to-rail analog switching capability with TTL-compatible control.
Technical Context
The 74LVC1G66GS,132 implements a CMOS transmission gate architecture with integrated Schmitt-trigger on the enable input, enabling reliable switching even with slow-rising control signals across its full 1.65–5.5 V VCC range. Its bidirectional Y/Z path operates symmetrically with no inherent source/drain distinction.
It exhibits flat ON resistance versus input voltage (RON(flat) ≤ 1.5 Ω at 5 V), low OFF-state capacitance (6.5 pF), and high isolation (−46 dB at 1 MHz, 600 Ω/50 pF load), making it suitable for precision analog signal paths where crosstalk and distortion must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VCC) | 1.65 V to 5.5 V - Enables direct interface with 1.8 V, 2.5 V, 3.3 V, and 5 V logic/system rails without level shifters. |
| ON Resistance (RON) | 6 Ω typical at VCC = 5 V - Ensures minimal signal attenuation and voltage drop (< 200 mV at 32 mA) in analog paths. |
| Switch Current | ±32 mA - Supports driving moderate loads such as audio codecs, ADC inputs, or sensor bias networks. |
| Enable Input Threshold | Schmitt-trigger with hysteresis - Tolerates slow edges and rejects noise on E pin across full VCC range. |
| Operating Temperature | −40 °C to +125 °C - Qualified for automotive under-hood, industrial control, and extended-environment applications. |
| OFF-State Leakage | ±200 µA max at VCC = 5.5 V - Maintains signal integrity in high-impedance circuits (e.g., sensor front-ends). |
| Charge Injection | 5.0 pC typical at VCC = 3.3 V - Minimizes glitch-induced errors in sample-and-hold or precision DAC output switching. |
Pinout & Package
XSON6 plastic extremely thin small outline package (no leads); 6-terminal surface-mount device; body dimensions 1.0 mm × 1.0 mm × 0.35 mm (SOT1202).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Y) | Independent I/O terminal | Bidirectional analog signal path; interchangeable with Z; no internal polarity or directionality. |
| 2 (Z) | Independent I/O terminal | Second bidirectional analog node; forms SPST switch path with Y when E is HIGH. |
| 3 (GND) | Ground reference | 0 V return for both analog signal path and digital control circuitry; must be low-impedance. |
| 4 (E) | Enable input (active HIGH) | CMOS/Schmitt-trigger digital control; accepts up to 5.5 V regardless of VCC; enables/disables Y-Z conduction. |
| 5 (n.c.) | Not connected | No internal connection; must remain unconnected on PCB; not to be tied to GND or VCC. |
| 6 (VCC) | Supply voltage | Power rail for analog switch and enable logic; bypassing with 100 nF ceramic capacitor near pin is recommended. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (1.65–5.5 V) | Eliminates need for separate voltage translators when interfacing mixed-voltage subsystems (e.g., 1.8 V MCU to 3.3 V sensor). |
| Low ON resistance flatness | ≤1.5 Ω variation across full input voltage swing at 5 V - preserves linearity in audio and instrumentation signal paths. |
| High OFF-state isolation | −46 dB at 1 MHz (600 Ω/50 pF) - prevents signal bleed between channels in multiplexed sensor or audio systems. |
| TTL-compatible enable | Accepts 5.5 V logic on E pin while VCC = 1.65 V - simplifies control from legacy 5 V microcontrollers or FPGAs. |
| ESD robustness | HBM > 2000 V, MM > 200 V - withstands handling and board-level ESD events without protection diodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS5A23157DCUR | 5-pin SC70 package; 0.9 Ω RON at 3.3 V; no Schmitt-trigger enable; −40 °C to +85 °C only. | Limited to commercial-temperature applications; lacks noise-immune enable for noisy environments. | Choose for lower RON in space-constrained 3.3 V systems where ambient temperature stays below 85 °C. |
| ADG801BRMZ-REEL7 | 6-pin SOT23 package; 0.3 Ω RON at 5 V; requires external VDD/VSS decoupling; −40 °C to +125 °C rated. | Higher cost; requires tighter layout control due to sensitivity to parasitic inductance on power pins. | Prefer when ultra-low RON is critical and board area allows larger SOT23 footprint; verify charge injection (1.5 pC) meets system settling requirements. |
Compared with TS5A23157DCUR and ADG801BRMZ-REEL7, the 74LVC1G66GS,132 uniquely combines Schmitt-trigger enable, XSON6 miniaturization, and full automotive-grade temperature range in a single low-cost package-making it optimal for noise-prone, space-limited, and extended-temperature designs.

FAQ
What is the maximum allowable switch voltage for the 74LVC1G66GS,132?
The 74LVC1G66GS,132 supports a switch voltage (VSW) range of −0.5 V to VCC + 0.5 V in both enable and disable modes. This rail-to-rail capability allows analog signals to swing fully between ground and VCC without clipping, provided the absolute maximum ratings (−0.5 V to +6.5 V) are not exceeded. The 74LVC1G66GS,132 maintains this range across its full operating temperature span.
Does the 74LVC1G66GS,132 require external pull-up or pull-down resistors on the enable (E) pin?
No, the 74LVC1G66GS,132 does not require external pull-up or pull-down resistors on the E pin because its enable input incorporates a Schmitt-trigger with built-in hysteresis. This design ensures clean, noise-immune switching even with slow-rising or floating control signals. The 74LVC1G66GS,132 remains OFF when E is held below VIH threshold (e.g., < 0.7×VCC at 5 V) and turns ON reliably above it.
Can the 74LVC1G66GS,132 be used to switch negative analog signals?
No-the 74LVC1G66GS,132 is not rated for negative signal voltages below GND. Its absolute minimum switch voltage is −0.5 V, and operation below GND risks latch-up or damage. For bipolar or AC-coupled signals with negative excursions, external clamping or level-shifting circuitry is required before connecting to the 74LVC1G66GS,132 Y or Z terminals.
How does temperature affect the ON resistance of the 74LVC1G66GS,132?
The 74LVC1G66GS,132 exhibits monotonic increase in ON resistance with rising temperature: RON rises by ~25 % from −40 °C to +125 °C at fixed VCC and current. At 5 V and 32 mA, typical RON is 6.2 Ω at 25 °C and increases to ~7.8 Ω at +125 °C. This behavior is documented in Table 8 and must be accounted for in precision gain or offset-critical paths using the 74LVC1G66GS,132.
Is the 74LVC1G66GS,132 pin-compatible with other variants like 74LVC1G66GV or 74LVC1G66GM?
No-the 74LVC1G66GS,132 uses the SOT1202 (XSON6) 6-terminal package, whereas 74LVC1G66GV uses SOT753 (5-pin SC-74A) and 74LVC1G66GM uses SOT886 (6-pin XSON6 with different pad layout). Pin counts and footprints differ: 74LVC1G66GS,132 has a dedicated n.c. terminal (pin 5) and VCC on pin 6, unlike the 5-pin variants. Direct PCB replacement is not possible without layout revision.
